You may find the rice a bit crunchy. It doesn't deal well with refrigeration.

The biggest problem I'm finding is the seaweed gets chewy. The issue here is that my DH likes sushi and occasionally I make it. He wants to take some to work for lunch however and it would be made the night before. He has asked if I can make enough for two days worth of lunches and I am skeptical about how it will hold up.
